## Step 1 — Understand the Basics
[HASH=3102]###[/HASH] What is a Crypto Drainer?
A **crypto drainer** is malicious software or infrastructure designed to facilitate the theft of cryptocurrency or digital assets.
Drainers commonly target:
*
**Cryptocurrencies**
*
**NFTs**
*
**Fungible Tokens (FTs)**
*
**EVM-compatible assets**
*
**Non-EVM ecosystems**, depending on the attack technique
The basic idea is simple:
**Victim → Fake Website → Wallet Connection → Malicious Request → Asset Loss**
---
## Step 2 — How Do you Make Money?
The first objective is usually to make the victim **trust the website**.
you may create websites that imitate:
*
NFT minting pages
*
Airdrop campaigns
*
Token claims
*
Cryptocurrency wallets
*
DEX interfaces
*
Giveaways
*
Popular Web3 projects
The fake website is designed to look legitimate.
[HASH=3102]###[/HASH] The deception usually follows this pattern:
**1. Create a convincing website**
↓
**2. Advertise a reward or opportunity**
↓
**3. Bring users to the website**
↓
**4. Encourage them to connect their wallet**
↓
**5. Present a transaction or signature request**
↓
**6. Victim unknowingly authorizes a malicious action**
The important point is that **connecting a wallet by itself does not automatically give a website unlimited access to your assets**. The dangerous part is what the user is subsequently asked to **sign or approve**.

## Step 3 — How Are Victims Reached?
Scammers need traffic, so they distribute links through places where Web3 users already spend time.
Common channels include:
[HASH=3102]###[/HASH] Social Media
* 𝕏 / Twitter
* Reddit
* Discord
* Telegram
* Snapchat
* Other online communities
[HASH=3102]###[/HASH] Direct Outreach
*
Phishing emails
*
Direct messages
*
Community messages
*
Fake support conversations
[HASH=3102]###[/HASH] The Social-Engineering Formula
> **Urgency + Reward + Trust = Higher Chance of Victim Interaction**
For example, a scam may claim:
**“You have been selected for an exclusive NFT.”**
or
**“Your wallet is eligible for an airdrop. Claim before the deadline.”**
The goal is to make the victim act **before carefully checking what they are signing**.

# Step 4 — The Wallet-Connection Stage
This is one of the most important stages of the attack.
A victim arrives at a fake website and sees something like:
[HASH=3102]###[/HASH]
“Claim Your Airdrop”
**Reward Available:**
`1,000 PROJECT Tokens`
**Status:**
Eligible
**Action:**
`Connect Wallet`
After connecting, the website may present additional requests.

##
Signatures & Transaction Requests
A wallet can display different types of requests.
For example:
[HASH=3102]###[/HASH] Message Signature
The wallet may ask the user to sign a message.
[HASH=3102]###[/HASH]
Transaction Approval
A more obvious warning sign is a transaction that requests permission to move or spend tokens.

Remember
[HASH=3102]###[/HASH] **Connecting ≠ Automatically Drained**
Simply connecting a wallet does not inherently transfer all of its assets.
Understanding signatures, approvals, transactions, and smart-contract permissions is one of the best ways to undertsand crypto-drainer scams.
